J l seWA GE- AND NIGHT-SOIL INCINERATING APPARATUS. v

;:,SP Lf-JGIEPICATION forming part of Letters Patent No. 352,857, dated November-16. 188 v r 5 as a fertilizer; and the objects of my improvement are to produce a simple and effective apparatus with flues so arranged as to remove all danger of the contents of the retort boiling over, while other flues will carry all the odors to a high chimney in close proximity to the apparatus. I attain these objects by the apparatus illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of an appa- 2 5 ratus constructed in accordance with my invention. Fig. 2 is a vertical section of the same. Fig. 3 is a horizontal section of the same on line 3 y of Fig. 2.

The foundation A and the casing A of the '30 apparatus are made of brick, iron, or of other suitable fire-proof material, and from the top of this casing is suspended a combined receiver and retort, B, in which garbage and night-soil are received through the opening B in the top, and carbonized at short intervals of time. The opening B is closed by a lid, a, hinged to the top, A, of the casing, that may also form the seat of the apparatus. To the under side of the seat is secured a conical funnel, a 0 that fits loosely within the top of the retort, to permit expansion and contraction of the parts without injury to the casing. The retort is retained centrally within the casing by vertical ribs 0 and C projecting inwardly from said 5. casing. The ribs 0 prevent the products of combustion issuing from the fire-chamber D from passing directly to the chimney E, but force them to descend along one side of the retort in-the flue E, and ascend on the opposite side through the flue E. The fire-chamber I ,7 v I Application filed February 23, 1886. Serial No. 192,882. (No model.)

has a cover, D,'of iron, brick, or other in-. combustible material. It has a grate,d, "and v under the latter is the ash-pit d; The admission of air into the fire-chamber is controlled by a vertically-movable valve d and the products of combustion on their way to the retort are controlled by a similar valve, 11*, and each one has a handle projecting above the cover D, through which they can be partly lifted to close the passage leading from the fire-chamber, and retained in that position by means of pins d entering said valve-handle, or by other suitable means.

The fire-chamber has a door, at, through which fuel can be. admitted therein, and the" ash-pit is also provided with a door. In the lower portion of the casing there is an opening, a for the admission of an iron prop, B to be placed vertically under the hinged bot-' tom B of theretort, and said opening is also closed by a door.

Cement or other suitable material is placed a between the bottom and the lower edge of the retort to seal it hermetically.

The prop B may be a plain bar of iron having one end resting upon the foundation of the apparatus and the other end forced under the bottom B or said prop may be made adj ustable in length by forming it of two bars placed end to end, one of them being screw-threaded and the other having a screw-threaded socket.

After the contents of the retort have been carbonized and incinerated, they are removed by knocking off the prop, opening the bottom 13 and dropping them into a suitable pan or vessel. In the side of the casing peepholes are made, so that the appearance of the retort while under the action of the fire may be' observed; but these holes are otherwise closed by swinging shutters a Gas-jets a may also be used at these points within the casing, to heat the retort or to increase the draft, and a gas-jet may also be placed within the chimney to increase its draft. This construction insures a constant strong draft to carry off any odors that may arise from the retort.

By having the current of flame issuing from the fire-chamber strike first the upper part of the retort, all danger of having the contents ICO boil up and overflow is removed, as the upper portion becomes carbonized first, and the carbonized material acts as a cellular stopper that, while permitting the steam to escape therethrough, arrests the thicker contents. The path followed by the flame and heated products of combustion, being first downward on one side of the retort and upward on the opposite side, takes all odors up the line.

Although the drawings show only one hopper leading into the retort, it is evident that two or more closets on different stories of a building may be made to discharge by suitable lengths of pipe into the same retort, or

that another closet and retort may be placed on the opposite side of the lire-chamber.

Having now fully described my invention, I claim' '1. The combination of a hopper, a vertical retort located thereunder, a casing i nclosing the whole retort, a fire-chamber located on one side of said hopper and retort and having valved passages in its sides to lead the heated products of combustion first down against one side of ther'etort and upward on the opposite side, substantially as and for the purpose described.

2. The combination of a hopper, a vertical retort Wholly inclosed in a casing and having a door in its lower end, and a fire-chamber located on the side of the upper end of said retort. substantially as and for the purpose described.

3. The combination of a hopper, a vertical retort having a door in its lower end, a prop under said retort, and a fire-chamber located on the side of the upper end of said retort, and a casing inclosing the whole, substantially as and for the purpose described.

In testimony whereof I atfix my signature in 0 presence of two witnesses.
